# acad: Prometheus vs Pandora interplay

<< Some of the most important rules we need to discover are about how to use technology and, just as importantly, how not to use it. >>

<< The great institutional economist Clarence Ayres wrote about how technology becomes incorporated into our lives in a way that is roughly equivalent to the way tribal societies use totems to interact with each other. >>

<< Every inventor is both a Prometheus stealing fire from the gods, and a Pandora unwittingly releasing a swarm of potential evils on the world. The competition of ideas between hype and doomsaying allows us to discover helpful rules which deal with both. >>

<< Technology doesn't come with a ready-made rulebook for how to use it. We have to discover this in a process of trial, error and argument. And for this the doomsayer is just as vital as the visionary. >>

# life: i tremiti (vortici?) previsionali di Giancarlo, by Alessandra Paola

<< Giancarlo Giorgetti, sottosegretario di Palazzo Chigi nel governo di Giuseppe Conte, pare abbia detto ai leghisti presenti nell' esecutivo di tenere una foto di Matteo Renzi come monito sulla scrivania. Per non dimenticare che quattro anni fa il Pd aveva conseguito il 40%, pari a 11 milioni di voti, alle elezioni europee >>

# gst: to model a system that can "collapse without warning"

<< Volcanoes progressively weaken and may collapse without warning through hydrothermal alteration. These dangerous mass wasting processes occur less-frequently than eruptions or lahars but the resultant mass flows can be large in size, posing risk to local residents, and businesses. >>

<< Collapses are often multi-hazard events, with even small-scale landslides capable of triggering eruptions or creating break-out lahars. >>

<< These kind of events demonstrated the greater need to understand and assess this process >>

# gene: newtic1 to regenerate limbs

<< The newt, a group of urodele amphibians, has outstanding ability to repeatedly regenerate various body parts >>

<< In this animal, when the limb is amputated, a cell mass named the blastema appears on the stump and eventually gives rise to a new functional limb >>

AA << identified an orphan gene Newtic1, whose transcripts significantly increased in the blastema. Newtic1 was expressed in a subset of erythrocytes that formed a novel clump (EryC) >>

<< When the limb was amputated, EryCs were newly generated in the stump and accumulated into a distal portion of the growing blastema. >>
